How often do YOU comment on things of which you have no clue?

Sometimes when I read Ars Technica, or other blogs both general and subject specific, which have a large commentator population, I get the impression that  a significant proportion of the commenters have no clue about what they write. In this article about the Police not liking Waze ‘tracking’ them you can tell that a LARGE part of the problem with some of the comments is that the people making those comments have never used Waze.

The Internet is a silly/horrible/awesome/frighting place.
